Hard to say for several reasons:
- came out earlier in the gen than NSMBWii
- Likely lower WiiU total sales
- NSMBWii was heavily bundled during the end of the gen
- There could be a sequel on the same platform
Thus my prediction will be under 20m, over 20m in case it will receive a bundle (which is likely).
